  • Product Overview

    Keep up to 500 square feet cool with the Whynter ARC-143MX 14,000 BTU Portable Air Conditioner. This dual-hose portable AC offers advanced air filtration and patented auto-drain technology, making it perfect for server rooms, data centers, and other areas where an efficient, low-maintenance portable AC is needed.

    Part of Whynter’s Go Green mission, the Whynter ARC-143 Dual Hose Portable Air Conditioner is Energy Star-rated, lead-free, and uses environmentally-friendly R-410 refrigerant. Three operating modes—Cool, Dehumidify, and Fan-only—let you enjoy quick and efficient cooling all year.

    Advanced Filtration

    The Whynter ARC-143MX Portable Air Conditioner comes with the 3M™ Antimicrobial High Air Flow (HAF) air filter that’s designed to remove particles such as dust, pet hair, and pet dander. An antimicrobial agent helps stop the growth of mold and mildew, and the micro-structured filtration media traps and retains particles—keeping them out of your space. This enhanced air filtration system is especially important for maintaining particle-free air around critical equipment in server rooms.

    Additionally, a pre-filter catches large particles while an advanced carbon filter removes smoke and other odors from your space. 

    Auto-Drain Technology  

    Whynter’s patented auto-drain technology uses and recycles moisture collected during the cooling process. Most if not all of the condensation will be recycled and exhausted, meaning little to no maintenance and manual draining is required.

    Under extremely hot conditions, the unit may not be able to recycle moisture quickly enough, so a backup reservoir inside the portable AC will be used to collect the condensation. The compressor will automatically stop if the reservoir is full, avoiding any chance of overflow. Your environment, and costly equipment, will be safe from possible damage.

    Additional Features

    • Programmable Timer: The Whynter 14,000-BTU Portable Air Conditioner is equipped with a 24-hour programmable timer for easy, set-and-go operation.
    • Auto-Restart: In the event of a power outage, the Whynter ARC-143MX restarts at the previously set function mode and settings when power is restored.
    • Thermostat Control: The Whynter 14,000-BTU Portable AC cycles on and off to maintain your desired temperature, which saves you on energy costs while cooling.
    • Auto-Drain Technology: This function uses a gravity drain system to automatically exhaust condensate water for hassle-free operation.
    • Remote Control: A handy remote control allows you adjust the speed, cool, timer, temperature, and dehumidifier settings and view the current operating mode in the LCD display screen.
    • Easy Portability: Rolling casters make it easy to move your Whynter 14,000-BTU Portable Air Conditioner from room to room.
    • Three Fan Speeds: Have more control over your room temperature and the unit’s sound level with 3 fan speeds (low, medium, and high).


    This low-maintenance Whynter 14000 BTU Dual Hose Portable AC unit has 3 operating modes and features that make it ideal for hot areas like server rooms as large as 500 square feet.

    What Customers Love

    • Advanced Air Filtration: A 3M™ Antimicrobial HAF filter removes allergens and air impurities from your air while cooling. 
    • Auto-Drain Technology: Under most conditions, the Whynter ARC-14S Portable AC if fully self-evaporative and requires no manual draining.  
    • Three Operating Modes: This model cools, dehumidifies, and provides fan-only operation.

      Relief from the heat

            Comments about Whynter ARC-143MX 14000 BTU Portable Air Conditioner with 3M Antimicrobial Filter:

            I bought this for use in our bedroom during a heat wave. I was super-impressed that it arrived the next day with no added shipping charges! The unit works well and the included kit connects to the window easily. It's too noisy to sleep with but i run it for a couple of hours before bed and get the room nice and cool. It would be better if it had some kind of handle - when you try to roll it on the carpet, with nothing to hang onto, it falls over and spills water. It exhausts most of the water but it could still use a larger water receptacle.

            Comments about Whynter ARC-143MX 14000 BTU Portable Air Conditioner with 3M Antimicrobial Filter:

            I use the AC in my sun room which has poor insulation and lots of windows. Average outside temp in my area S. CA is 105 in summer. I can now use this room year round. I've been using it for about 3 weeks and am still waiting to see if there is a reduction or increase in my Electric bill....praying for reduction! The AC cools room very comfortable and I love the remote/ timer feature. I can set it to shut off when I want. I run the AC at about 73 degrees and it works great. Only negative is when draining the water from base, there is no hose attachment...sticking a very shallow pan and having to tip the heavy unit is tough for me physically. I wish there was a better drain system. Overall, I love the unit...wish it came in white so it blended with my room decor, but that is superficial. Cools great and ease of use is great...I ran hoses out an unused dog door and avoided all window installation issues...just had to insulate around hoses...easy to remove and roll away in winter.

            I use this air conditioner in the living room. Cools the room fast and evenly. Temperature display is off about 4-6 degrees from actual room temperature. The window kit design needs improvement. Performs well in cooling.

            This is not your budget product. It's on the high side, but if your looking for fast cold air, it'll come through. The 3M filter is great too if you have pets. Not a full blown purifier, but it definitely handles a good amount of dander and fur. I'm glad I paid for exactly what I need and more.

            • Cooling if no window unit

            Comments about Whynter ARC-143MX 14000 BTU Portable Air Conditioner with 3M Antimicrobial Filter:

            My windows can't handle a window air conditioner without major hassles. Great to have a solution I can use for the odd week of too hot weather then easily put away again. Nice to have the option of cooling the bedroom area at night and the wife's home office during the day. I like the ARC-143MX. The 3M filter instead of the carbon one (ARC-14S) means more air flow but no odor removal. Pick the model on that difference. Cools my 13x13 bedroom down from 81 to 72F in 30 minutes. Outside temperature usually dropping from 87 to 80 at the same time. 72F to 64F takes longer. I appreciate not having to dump out water! Casters roll easily. Handles are just indentations on the sides of the shell: wouldn't take much to drop and lack of anything to grip makes two person carry by handles an iffy thing to do. Not designed to go upstairs at night and downstairs every morning. Shell does not handle torque stress well. Compressor noise is a little too much for me to sleep next to but quiet enough to hold a conversation while standing around the ARC-143MX. The window kit is plain PVC: it needed some caulk and stick-on foam strips to not let in outside air and bugs. Would be better if window kit was designed so intake and exhaust could be spaced as far apart as the width of the window opening instead of fixed at a few inches apart. Remote easier to use than front-facing controls on unit because unit display awkward to read unless kneeling. Unit is tall enough that the cold air is mixing in the upper part of the room and not getting trapped by the bed or couch. Power cord length is good but I can see where longer would come in handy. For a product in this price range, the timer should be upgraded to do daily scheduled on and off timings.
            I like the ARC-143MX and hope the next model gets a few tweaks.
